Statement of the Problem. Modern routing protocols for wireless sensor networks (WSNs) of distributed territorial security systems (DTSS) fail to ensure resilience and connectivity preservation under conditions of dynamic intentional electromagnetic interference (IEMI) from electronic warfare (EW) assets. Among the tasks of maintaining interference immunity in general-purpose WSNs, the most promising approach identified is the routing method based on a modified distance matrix using the Floyd-Warshall algorithm. However, this method does not account for the stochastic nature of real-world interference, its time-frequency variability, and adaptive behavior, while also being characterized by unacceptably high computational complexity and energy costs for resource-constrained sensor nodes. This creates a critical gap between the required network reliability and the capabilities of existing algorithmic solutions.

Purpose. To evaluate the spatiotemporal and energy characteristics of a WSNs of a DTSS, routed under conditions of intentional interference using a modified distance matrix with the Floyd-Warshall algorithm.

Results. The main indicators of the quality of WSN routing under conditions of intentional interference using a modified distance matrix with the Floyd-Warshall algorithm are identified and their numerical evaluation is provided. The boundary conditions for applying the WSNs routing method based on a modified distance matrix for reconnaissance and alarm complexes (RSAC) of a DTSS are determined.

Practical significance: the identified boundary conditions allow determining the practical application area of the WSN routing method based on a modified distance matrix for RSAC of a DTSS.
